Best type of boa

[Vypyrz]

The Dumeril's seems pretty small and most places say they won't break 6 feet, but when people post weights they're 16-20 lbs. That's 7000 grams!

Males vs. Female

I want a boa that's puppy dog tame that's the smallest size step up from a BP.

Do BCI prefer to have height to their enclosure or are they happy in tubs?

#1) Some of the smallest of the BCI's are:
-Caulker Cay
-Tarahumara
-Tamaulipas

#2) Most BCI are semi-arboreal, and will gladly perch on any elevated items
that you provide them.
